“…There were even more IPSS reductions in the MRA group (À11 points with MRA vs. À7 points without MRA, p < 0.001) after PAE. 15 A similar study with randomized controlled clinical trial design, on 100 men who were randomly assigned to MRA and non-MRA groups, showed that MRA led to shorter PAE detection times and lower radiation dose. MRI evaluations can also be informative in the determination of the gland configuration.…”

Prostatic artery embolization (PAE) is a safe and effective treatment for benign prostatic hyperplasia. Patient evaluation is a critical and important part of this growing practice. History taking should include symptoms score evaluations for lower urinary tract symptoms, erectile function, and prostatitis symptoms score. The objective evaluations commonly include measurement of prostate specific antigen, postvoid residual volume, and uroflowmetry as well as urodynamic studies in selective patients. Imaging evaluation may include computed tomography angiography or magnetic resonance angiography, elucidating prostate volume, prostate gland morphology, vasculature, and prostate cancer. With evolving knowledge on PAE, we aim to discuss patient evaluation and selection based on updated evidence and discuss specific scenarios.

“…To facilitate and troubleshoot vascular anatomy in complex anatomical fields such as the pelvis, different imaging modalities and techniques have been described. Pre-procedural CT angiogram [26] and pre-procedural MR angiography (MRA) [27] with different benefits are described but are not within the scope of this review. Several other studies propose variations of the intra-procedural CBCT [21,22,24,[28][29][30] and additional virtual injection methods [20] in order to improve identification of prostatic arteries and treatment techniques (Tabe 1).…”

Prostatic artery embolization (PAE) has proven to be an efficacious treatment for urinary symptoms of benign prostatic hyperplasia. PAE is performed in a complex and challenging anatomical field which may pose difficulties from procedural standpoint. Cone beam computed tomography (CBCT) has been proposed as an invaluable tool during the PAE procedure. A review of different techniques and advancements, as well as demonstration of CBCT benefits via a pictorial overview of the salient examples is lacking. The techniques of CBCT are discussed herein and the virtual injection technology as an advancement in CBCT is discussed. To show the merits of CBCT in PAE, a pictorial overview of various clinical scenarios is presented where CBCT can be crucial in decision making. These scenarios are aimed at showing different benefits including identification of the origin of the prostatic artery and avoiding non-target embolization. Other benefits may include ensuring complete embolization of entire prostate gland as angiographic appearance alone can be inconclusive if it mimics a severely thickened bladder wall or ensuring adequate embolization of the median lobe to provide relief from “ball-valve” effect. Further examples include verification of embolization of the entire prostate when rare variants or multiple (> 2) arterial feeders are present.
